JEROME WHEELOOK, OF WORCESTER, MASSACHUSETTS.

INJECTOR-CONDENSER.

SPECIFICATION forming part of Letters Patent No. 242,088, dated May 24, 1881. Application filed April 14, 1881. (No model.)

To all whom it may concern Be it known that I, JEROME WHEELooK, of the city and county of Worcester, in the State of Massachusetts, have invented certain new and useful Improvements in Injector- Condensers for Steam-Engines and I do hereby declare that the following specification, taken in connection with the drawings furnished and forming a part of the same, is a clear, true, and complete description of the several features of my invention.

The prime object of my invention is to provide in what are known as siphon-condensore for a more intimate admixture" of the steam with the injected water than has heretofore been attained. Instead of delivering the steam in a solid column from a sin gle-mouthed funnel-shaped nozzle, as heretofore, I deliver it not only in a central solid column, but also, in addition thereto, in one or more annular columns concentric with the central column, so that, while I have the central or driving column immediatelyIabove the nozzle through which the water and steam are driven downward from the condenser-head, I have also the one or more annular columns of steam, which impinge against the interior inclined walls of the funnel-shaped casing, and therefore commingle intimately with water as it passes downward along said walls. I have also devised certain features of construction of more or less practical value, all of which, after a full and detailed description, will be set forth specifically in the several claims hereunto annexed.

Referring to the drawings, Figure 1 is a central vertical section of a condenser-head embodying the several features of my invention. Fig. 2 is a lower-end view of the steam-nozzle detached from the head.

The curved exhaust-pipe A communicates with the engine-cylinder in the usual manner. The horizontal pipe B communicates with the cold-water source, and the vertical pipe (3 extends to the'hot well, all as heretofore. The

ejector-nozzle a is constructed and arranged in accordance with certain Letters Patent heretofore issued to me, but so far as relates to my present invention any variety of ej ector-nozzles may as well be employed. The annular waterchamber D is preferably constructed as shown, and separately from the conical chamber E ever desirable.

and united thereto by bolts, so that at any time the chamber E may be removed, and also the exhaust-pipe A without disturbingthe coldwater connections.

The steam-nozzle F is novel in its construction in that it has, in addition to the usual central delivery-aperture, b, one or more concentric annular apertures, 0, separated by the annular partitions c, which are connected with walls of the central aperture, with each other, and with the main or upper portion of the nozzle by radial webs o of which there may be any desired number; but I find that three are ordinarily ample. The upper end of the nozzle isv provided with an outwardly-extended flange, d, which occupies an annular recess in the top of the water-chamber D, so that when the exhaust-pipe is bolted to the lattersaid nozzle is firmly secured in position, but admits of the ready disengagement of the parts when- I have shown but two of the annular apertures 0, but one will answer a good purpose in some cases, while in others more than two will be desirable.

It will be seen that a central solid column of steam will proceed directly toward and into the ejector-nozzle a, but that each of the annular columns more or less broken by the webs will impinge against the inner inclined sides, 6, of the chamber E, and intimately commingle with the water flowing from above down those sides, and thus insure as prompt condensation of the steam as will be possible with water at available low temperatures used with this class of apparatus. As a result, all other conditions being equal, less water is required than with the solid steam-column, and sequentially the water from the condenser is proportionally higher in temperature.

It is of practical importance to have the interior of thechamber E as fully occupied by the steam-nozzle as possible, because space in said chamberis thereby occupied by hot steam, which would otherwise be tenaciously occupied by air, which, if present, would lessen the degree of attainable vacuum.

I am aware that heretofore condensers have been provided with a water-chamber and a series of small pipes extending through said chamber for the passage of exhaust-steam into the condenser.

Having thus described m y invention, I claim ter-ch amber, and conical chamber terminating 10 as new and desire to secure by Letters Patat an ejector-nozzle with the steam-nozzle proent vided with the central delivery-aperture and 1.
